P chart of percentage tags that are positive

Are stories becoming more positive?

In this chart the percentage of positive tags are plotted for each month. See About for more about tags. By making this a control chart, any changes in the central percentage or unusual variation can be detected. A p chart is the most appropriate chart for percentages and change or variation is detected by looking for these features:

1. A single point outside the (3 sigma) control limits.
2. Eight consecutive points above or below the centreline.
3. Six consecutive points increasing or decreasing.
4. Two out of three consecutuve points in the outer one-third (2 to 3 sigma).
5. Fifteen consecutive points in the inner one third.

The first 20 months are used to calculate the centreline. New centrelines are calculated from where eight consecutive points are above or below the centreline.
